IRONMAN 70.3 Dallas-Little Elm 2027
A 70.3 at Little Elm near Dallas: a swim in Lewisville Lake, a bike through quiet North Texas countryside and a three-loop run on a crushed-gravel nature trail.
23 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.

Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“The run is on hard-packed crushed gravel and not tarmac, so include some training on a similar surface. The organiser gives about 427 m of climbing on the bike.”
